If you ever want to get an S-trim get it now, it will save you a bunch of money over upgrading the a-trim to an s-trim later. The s-trim comes with the inline t-rex fuel pump. You might just need to add bigger injectors for fuel requirements. I'm not sure how much hp the 24 lbs can handle.
Also the Vortech only claims 70 hp gain with a-trim. That won't get you 400 hp from your current 316.
